OBJECTIVE Postoperative atrial fibrillation is a common complication after cardiac surgery, with an incidence as high as 20-50%. Increased age is associated with a significant increase in postoperative atrial fibrillation risk. This common complication is associated with higher morbidity and mortality rates. The aim of this study was to assess the efficacy of nebivolol in preventing atrial fibr...

Nebivolol is a third-generation beta blocker that exerts selective antagonistic activity on β1 receptors. It has vasodilating properties that result from direct stimulation of endothelial nitric oxide synthase. Nebivolol is indicated for the treatment of hypertension and heart failure, and is generally well tolerated. In this article, we report a case of an infant who was admitted to the Pediat...

The mechanisms for the vascular actions of vasodilatory b-blockers remain undetermined. For some kinds of b-blockers, the involvement of nitric oxide (NO) has been suggested. We studied the effects of vasodilatory b-blockers on renal perfusion pressure (RPP) and NO release in the rat kidney. Infusion of bopindolol, celiprolol, and nebivolol caused a dose-dependent reduction in RPP and an increa...

Endothelial dysfunction is more prevalent in African Americans (AAs) compared with whites. The authors hypothesized that nebivolol, a selective β1 -antagonist that stimulates nitric oxide (NO), will improve endothelial function in AAs with hypertension when compared with metoprolol. In a double-blind, randomized, crossover study, 19 AA hypertensive patients were randomized to a 12-week treatmen...

BACKGROUND We investigated whether carvediolol or nebiovolol with vasodilator properties will produce different effects on diastolic function of the left ventricle (LV) in heart failure (HF) with low ejection fraction (EF). METHODS Sixty-one non-ischemic HF patients with EF ≤40% randomly received carvedilol (n = 31, 16 male) or nebivolol (n = 30, 19 male). Clinical and echocardiographic evalu...

Nebivolol is a highly selective beta1-adrenergic blocker that also enhances nitric oxide bioavailability via the L-arginine-nitric oxide pathway, leading to vasodilation and decreased peripheral vascular resistance. It is marketed in Europe for the treatment of hypertension and heart failure and is currently being reviewed for use in the US by the Food and Drug Administration. Nebivolol appears...

BACKGROUND Carvedilol and nebivolol have favourable properties such as anti-oxidative effects in addition to other beta-blockers. However, which of these drugs is more effective on oxidative stress is unclear. AIM To compare the effects carvedilol and nebivolol on oxidative stress status in non-ischaemic heart failure (HF) patients. METHODS We included 56 symptomatic non-ischaemic HF patien...

BACKGROUND we investigated renal effects of nebivolol, a selective β(1)-receptor blocker with additional antioxidative ability, in spontaneously hypertensive rats (SHR) where increased salt intake induces oxidative stress and worsens renal function as a result of further activation of the renin-angiotensin and sympathetic nervous systems. METHODS male SHR were given an 8% salt diet (HS; n = 2...

AIM To investigate the effect of substituting beta-blockers with nebivolol on the erectile function of patients suffering from essential hypertension. METHODS Forty-four young and middle-aged men (31-65 years) with essential hypertension visited our outpatient clinic and took beta-blocker treatment (atenolol, metoprolol or bisoprolol) for more than 6 months. All the patients completed a quest...
